一种海湾扇贝产卵和孵化的方法
摘要：
一种海湾扇贝产卵和孵化的方法，其特征是产卵前先设置一预产卵池，把海湾扇贝种贝放入预产卵池30-40分钟，并进行排便及其它分泌物，让海湾扇贝排精5-15分钟；有个别的种贝产卵时，将种贝移入产卵池中产卵，当池中卵密度达到50-60个/ml后，将全部种贝移入另一产卵池中继续产卵；当有部分种贝排精后，马上移入他池，继续培养；把上述产卵池的卵液分出一部分放入另一产卵池中，加入与产卵水温相同的过滤海水，进行分池洗卵培育，捞出泡沫后，进行孵化，孵化水温为22-25℃。本方法提高了海湾扇贝受精卵的孵化率和育苗的成功率，只需小量的种贝就可满足育苗车间所需的幼虫数，降低了海湾扇贝种贝蓄养的数量，降低了生产成本，使海湾扇贝育苗达到稳产高产的水平。
摘要（英）：

The present invention relates to a bay scallop oviposition and hatching method. Said method includes the following steps: before oviposition, firstly seeting a preoviposition pool, placing seed scallops into said preoviposition pool for 30-40 min, making defecation and discharging other secrete, making bay scallops discharge spermatozoa for 5-15 min; when the individual seed scallop oviposits, placing the seed scallop into oviposition pool to make oviposition, after the ova density is reached to 50-60/ml, placing all the seed scallops into another oviposition pool to make continuous oviposotion; after part of seed scallops discharges spermatozoa, promptly placing said seed scallops into other pool to make continuous culture; then washing ova, making cultivation and making hatching, the hatching water temperature is 22-25deg.C.
